Two more disappearances, both linked to Ai Weiwei, have come to light in China amid a widening crackdown on dissidents in the country.

The lawyer, Liu Xiaoyuan, posted a message on a microblog at 8 p.m. Thursday saying he was being "followed by identified people." His phone is currently switched off, the Guardian said.

In addition, a designer from the company handling Ai Weiwei's affairs was taken by police six days ago, according to supporters.

Liu Zhenggang, 49, was taken from his Beijing home on 9 April and no one has been able to reach him since. Liu worked for FAKE, the design and architecture firm that belongs to the Ai's wife.

These are the latest detentions in what is proving to be one of the toughest crackdowns in China in recent years. The wave of brutality appears to have been sparked by anonymous calls online for "Jasmine Revolution" protests inspired by the Middle East uprisings.
